Given numbers are 821,626,102,788,730

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 821,626,102,788,730 is 3769439287260.

Find LCM of 821,626,102,788,730 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 821 x 313 x 51 x 394 x 365 = 3769439287260

Therefore, the lowest common multiple of 821,626,102,788,730 is 3769439287260.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

821 x 626 x 102 x 788 x 730 = 30155514298080

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

821 : 1, 821

626 : 1, 2, 313, 626

102 : 1, 2, 3, 6, 17, 34, 51, 102

788 : 1, 2, 4, 197, 394, 788

730 : 1, 2, 5, 10, 73, 146, 365, 730

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,626,102,788,730, is 1.

Now, the common factors can be found like this.

821:821

626:2x 313

102:2x 3x 17

788:2x 2x 197

730:2x 5x 73

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2 = 8

Therefore, the value for common factors is 8.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 30155514298080/(1x8)

LCM = 30155514298080/8

LCM = 3769439287260

Thus, we can understand that the LCM of 821,626,102,788,730 is 3769439287260.
